You forgot to bundle “solution to corporate greed” along with the other things you say we’re going to need. Today’s keepers of “automation, robotics, AI, and related productivity enhancements” are for-profit corporations who are beholden to their managers and shareholders. It’s those two groups who act as beneficiaries of the soils; certainly not public pension funds.
I find it rather naive to expect a causal link to materialize between corporate profits attributable to automation and solvency of government pension schemes. Corporations certainly wouldn’t do anything to help humans out of the goodness of their heart.
1. Things become cheaper. Maybe you don't need a car anymore since robot taxis are much more affordable. Houses become cheaper to produce, as well as the objects inside. Food is cheaper to produce.
2. Stocks in the "greedy corporations" do better, growing retirement savings.
3. Taxes on the profits grow, which can contribute to pension plans.
